Hi Pete
That's my plan and i will check the timing, but as I am purchasing from the club anyway I might as well get a replacement coil, its not exactly expensive! plus will save on postage. I will add plugs to the shopping list! The new cap and rotor have improved the symptoms but not solved them,
To my mind that leaves plugs, coil and possibly the electronic ignition. If I have all three to hand and keep my "Claasic Car" fingers crossed, the problem will go
